Oystein,

I apologize, I misunderstood your problem. I don't have a solution for you.

In fact, I have a feature in our application that could benefit from an algorithm that generates a shape from the union of circles.
 
Cheers,
David

Thanks for the tip on scaling, that will come in handy, but I'm no
closer to a solution to my real problem; constructing the intersection
region from the circles.

Do you have any input on the approaches I suggested?
